    I was doing a little bash today and after I was done I noticed one of my batteries was crushed. Now the cells are still balanced and all but I don't know if its still safe to use.

    @-Dusty- that's more than just a little crushed. I know it sucks to have to replace nice LiPo batteries like SMC, but if it was me - I'd be replacing it.

    Sucks too because this is like the 4th or 5th run with them

    I might just go with single 6s or something. These 3s are pretty heavy to be stacking on top each other I guess

    I am in 100% agreement with WoodiE. Lipo's are not to be taken lightly.

    The plastic isn't broken it just got pushed up at the seam. I still don't trust it but I wonder if the hard case is half empty. It is a 3s in a huge case.

    I don't know. I probably wont order this type again though

    Peal the stickers then fully separate the case. Just do it outside in a place you can kick it away from you in a hurry in case a cell gets punctured.

    I peeled the stickers but the side that is pushed in is stuck in there pretty good. I cant seem to separate it

    It's probably glued together or ultrasonically welded. Tough to get apart without slipping and poking a hole in the lipo underneath.

    Remember when you were a kid and your friend dared you to put a 9 volt battery on the tip of your tongue????

    Yeah that was the last time you ever needed to mess with batteries, that one needs to be put out of service!

    I remember being a kid, cutting the cord off a broken blender, separating the wires, stripping the ends, then plugging it in and "welding" tin-foil.

    I was not a wise kid. ;)

    That's not crushed. That's effin demolished man.
    I wouldn't trust that near my RC or charging station/home.

    Also, don't go for a 6s pack especially for these kind of reasons. One small damage and you'll have to replace an etire 6 cells worth of battery. As opposed to only 3 cells when you have them in dual channel.

    Well at the moment I just bought a couple 4s 90C 7400mah to play around with. They are not too heavy and for playing around my yard and don't really need the 6s speeds for that. I do want to go back to 6s for bashing though. Im not sure if I will go with 2x3s or single 6s. I don't really want to get another 3s like that one. They are too heavy to be stacked. I might try to configure some sort or brace or something over the bottom battery. Just cut and bend a aluminum sheet.

    Ill figure something out

    Well, I did the salt water thing for 3 days. Today I punctured the cells with two nails then put the lipo in a coffee can full of sand.

    Should be good now?
